CLARK F. THAYER, OF ERIE, PENNSYLVANIA.

BAB Y-C ARRIAG'E Specification of Letters Patent.

Patented Feb. 23, 1909.

Application filed October 12, 1908. Serial No. 457,295.

To all whom it may concern:

Be it known that I, CLARK F. THAYER, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Baby-Carriages; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.

My invention relates to improvements in baby-carriages and has for its object the construction of a baby carriage which can be readily folded together when not in use. To accomplish this result I construct the running gear of the carriage, and the sides of the seat so that they will fold together on the release of the braces of the sides of the seat, and the movement of the handle forward over the seat.

The construction of my improved baby carriage and the operation of the mechanism thereof are hereinafter fully set forth and explained and illustrated in the accompanying drawings, in which:

Figure 1 is a view in side elevation of a baby-carriage embodying my invention. Fig. 2 is a rear end view in elevation of the same. elevation of the same. Fi 4 is a view of the under side of my lmproved baby carriage. Fig. 5 is a side view of my improved baby-oarriage folded up. Fig. 6 is an end view of the same.

In these drawings illustrating my invention, A represents the frame of the carriage body, to the rear end of which there is hinged a handle B. Intermediate of the frame at each side of the carriage body A, I pivot on ivots c uprights C C forming the fronts of the sides of the carriage body, and to the upper ends of the uprights 0 bars D D are pivoted at their front ends by means of ivots d and at their rear ends they are pivoted to the handle B, and from the pivots d braces E pivoted thereon extend diagonally to the rear end of the frame A where their rear ends removably engage notches a therein, and these braces E also engage at their rear ends with guide rods F secured at their front ends to the sides Fig. 3 is a front end view inof the frame A, their rear ends f passing down through the rear cross-bar A of the frame A where they are provided with spiral springs f, and their ends contact with the ends of a centrally hinged tripping bar G pivoted to supports a a on the cross-bar A of the frame.

One of the sections of the tripping bar G has an upward extension g, which, when depressed, operates the trippin -bar G to raise the rear ends of the guide-bars F and the braces E out of the notches a in the sides of the frame A, so as to permit the rear ends of the braces E to slide fogward on the guide-bars F as and for the purpose hereinafter set forth.

The wheel sup orts H are so pivoted to the side-bars of t e frame A, that they can be folded inward under the carriage body frame, the wheels H on one side folding over the wheels on the other. The axes of the wheels H are pivoted on suitable bearings in these supports H in the usual manner.

To the insides of the lower ends of the supports H at one side of the carriage body I secure a rod I curved at its ends but havin the intermediate portion thereof straight, and at the other side of the carriage body I secure a like rod I which however has an intermediate offset 2' therein.

On the uprights O 0 there are extensions C C extending downwardly below their pivotal connections with the frame A, and secured to the lower ends of said extensions C C there is a cross-bar J provided with slots j j at its ends embracing the rods I and I, so that when the upper ends of'the upri hts C are moved forward in the operation 0 folding the carriage together, the crossbar J is moved toward the rear end of the carriage along the rods I and I in the slots j j therein, and as the slot j engages the offset i in the rod I it operates on said rod to fold the wheel supports H H to which the rod I is secured inward in advance of the operation of the cross-bar J upon the rod I to fold the wheel supports H H on that side of the carriage inward, so that when the carriage is folded up the wheels on one side of the carriage are folded under the wheels on the o osite side of the carriage, as illustrate in Figs. 5 and 6.

To the sides of the rear art of the frame A, I pivot a U-shaped mem er K which normally extends downward so as to form a brace between the rear ends of the rods I and I, and pivoted to the sides of the front part of the frame A, I pivot a like U-shaped member K which also normally extends downward so as to form a brace between the front ends of the rods I and I, both of which U-shaped braces are clearly shown in Figs. 2 and 3. To the extensions C on the uprights C below the pivotal connections 0 thereof with the frame A, I pivot links I; which extend back to and are pivoted to the arms of the U-shaped brace K, so that as the extensions C are moved backward the links L move the U-shaped brace K back from between the rear ends of the rods I I as illustrated by dotted lines in Fig. 1, and to the uprights C above their pivotal connections 0 w1th the sides of the frame A, I pivot links L which extend forwardly to and are pivoted on the arms of the U-shaped brace K so that as the uprights C move forward the links L move the U-shaped brace K forward, from between the front ends of the rods I I as illustrated by dotted lines in Fig. 1.

The back M of the carriage body is pivoted at its lower end to the sides of the frame A, and is provided with a U-shaped brace N the arms of which are pivoted in the arms of the handle B, and onthe back of the part M there are slotted guides m provided at their upper ends with stops m in which guides the U-shaped brace N operates so as to hold the back M at such angle to the body of the carriage as may be desired.

In the operation of folding the carriage together as illustrated in Figs. 5 and 6, the rear ends of the side brace-s E are released from the notches a in the sides of the frame A b depressing the tri ping bar G; the han le B is then moved fbrward which operates through the bars D D to move the upper ends of the u ri hts C G forward and the extensions 0' t 1916011 backward. The first effect of this is to move the U-shaped braces K and K from between the ends of the rods I and I so as to allow the wheel supports H and the wheels H carried thereby to be folded inward. The further forward movement of the handles B operating through the parts D, C and C, operates to move the slotted bar J backward under the carriage body and as it contacts with the offset z' in the rod I it folds the wheel supports to which the rod I is secured inward in ad vance of its action upon the rod I to turn the wheel sup ort-s to which it is attached inward, anti the further movement of the handle B down upon the top of the carriage body completes the operation of folding of all the parts together. For opening up the carriage for use the movement of the handle B is simply reversed.

In Fig. 1, I have illustrated in broken lines the different adjustments of which the back M is capable, and I have also illustrated in broken lines the movement of the handle B, the back M, and the parts D, C, G E L L, K and K during the commencement of the folding operation.

Having thus described my invention so as to enable others to construct and operate the same, what I claim as new and desire to secure by Letters-Patent is:
